5 matches in recent times where Roger Federer lost after winning the first set

3. Roger Federer vs John Millman (2018 US Open 4th round)

2018 US Open - Day 8

This was probably the only Federer loss where he bowed out in a bizarre fashion and looked as though he wanted to leave the court as soon as possible. During the post-match press conference, Roger Federer said that he couldn't find his rhythm as the temperature in Arthur Ashe stadium was scorching.

But credit shouldn't be taken away from Millman as he fought against all odds to beat Federer 3-6, 7-5, 7-6, 7-6.

4. Roger Federer vs Kevin Anderson (2018 Wimbledon quarter-final)

If there is any match in recent times that every Federer fan would like to forget, it would be the Wimbledon quarter-final match against Kevin Anderson.

Federer took a comfortable two-set lead before falling to the giant 2-6, 6-7, 7-5, 6-4, 13-11. It almost felt a little monotonous in the last set where each player tried to hold and the match seemed likely to continue forever.

But once again, it was Federer who lost his serve and with it the match.

5. Roger Federer vs Thanasi Kokkinakkis (2018 Miami Open)

After an enthralling Indian Wells final against Juan Martin del Potro, Federer looked physically spent and he lost in the second round of Miami to the Australian Thanasi Kokkinakis.

Federer took the first set comfortably but lost his shape in second, and Kokkinakis took charge from there on. He defeated Federer 3-6, 6-3, 7-6 to register his career's first win against a top 10 player.
